Padres first baseman Yonder Alonso has only appeared in one game this month due to a back injury and now he might be done for the season.

Jay Paris of MLB.com reports that Alonso was diagnosed with a stress reaction in his back after undergoing a bone scan. He won’t be with the team at the start of their nine-game road trip and Padres assistant general manager Josh Stein said that there’s “an absolute possibility” he won’t make it back by the end of the season.

Alonso, 28, is batting .282/.361/.381 with five home runs and 31 RBI over 402 plate appearances this season. The former top prospect has never hit more than 10 home runs in a season in the majors, so he doesn’t exactly fit the mold of a slugging first baseman, but he has shown an ability to hit for average and get on base when healthy. He’s making $1.65 million this season and will be arbitration-eligible for the second time this winter.
